Here is our original system
\n" ); document.write( "(i) $\"2x-4y=8\"$
\n" ); document.write( "(ii) $\"1x-2y=4\"$
\n" ); document.write( "step 1 - multiply (ii) by -2 to get
\n" ); document.write( "(iii) $\"-2x+%2B+4y+=+-8\"$
\n" ); document.write( "add (ii) and (iii) to get
\n" ); document.write( "(iv) $\"0+%2B+0+=+0\"$
\n" ); document.write( "this mans that we have the same equations but in disguise.
\n" ); document.write( "These equations are \"dependent\" \n" ); document.write( "

\n" );
